Neutron Scattering: Applications in Chemistry, Materials Science and Biology, Volume 49, provides an in-depth overview of the applications of neutron scattering in the fields of physics, materials science, chemistry, biology, the earth sciences, and engineering. The book describes the tremendous advances in instrumental, experimental, and computational techniques over the past quarter-century. Examples include the coming-of-age of neutron reflectivity and spin-echo spectroscopy, the advent of brighter accelerator-based neutron facilities and associated techniques in the United States and Japan over the past decade, and current efforts in Europe to develop long-pulse, ultra-intense spallation neutron sources. It acts as a complement to two earlier volumes in the Experimental Methods in the Physical Science series, Neutron Scattering: Fundamentals(Elsevier 2013) and Neutron Scattering: Magnetic and Quantum Phenomena (Elsevier 2015). As a whole, the set enables researchers to identify aspects of their work where neutron scattering techniques might contribute, conceive the important experiments to be done, assess what is required, write a successful proposal for one of the major facilities around the globe, and perform the experiments under the guidance of the appropriate instrument scientist.
An engaging critique of the science and metaphysics behind our understanding of the universe  The James Webb Space Telescope, when launched in 2021, will be the premier orbital observatory, capable of studying every phase of the history of the universe, from the afterglow of the Big Bang to the formation of our solar system. Examining the theoretical basis for key experiments that have made this latest venture in astrophysics possible, Bjørn Ekeberg reveals that scientific cosmology actually operates in a twilight zone between the physical and metaphysical. Metaphysical Experiments explains how our current framework for understanding the universe, the Big Bang theory, is more determined by a deep faith in mathematical universality than empirical observation. Ekeberg draws on philosophical insights by Spinoza, Bergson, Heidegger, and Arendt; on the critical perspectives of Latour, Stengers, and Serres; and on cutting-edge physics research at the Large Hadron Collider, to show how the universe of modern physics was invented to reconcile a Christian metaphysical premise with a claim to the theoretical unification of nature. By focusing on the nonmathematical assumptions underlying some of the most significant events in modern science, Metaphysical Experiments offers a critical history of contemporary physics that demystifies such concepts as the universe, particles, singularity, gravity, blackbody radiation, the speed of light, wave/particle duality, natural constants, black holes, dark matter, and dark energy. Ekeberg’s incisive reading of the metaphysical underpinnings of scientific cosmology offers an innovative account of how we understand our place in the universe.
From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That's just what Paul J. Nahin's guide provides. An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin's equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way. If you ever wanted to set up the latest and greatest grandfather paradox--or just wanted to know if the time-bending events in the latest pulp you read could ever happen--then this book is for you.
Magnetic fields are important in the Universe and their effects contain the key to many astrophysical phenomena that are otherwise impossible to understand. This book presents an up-to-date overview of this fast-growing topic and its interconnections to plasma processes, astroparticle physics, high energy astrophysics, and cosmic evolution. The phenomenology and impact of magnetic fields are described in diverse astrophysical contexts within the Universe, from galaxies to galaxy clusters, the filaments and voids of the intergalactic medium, and out to the largest redshifts. The presentation of mathematical formulae is accessible and is designed to add insight into the broad range of topics discussed. Written for graduate students and researchers in physics, astrophysics and related disciplines, this volume will inspire readers to devise new ways of thinking about magnetic fields in space on galaxy scales and beyond.
Tensors, Relativity, and Cosmology, Second Edition, combines relativity, astrophysics, and cosmology in a single volume, providing a simplified introduction to each subject that is followed by detailed mathematical derivations. The book includes a section on general relativity that gives the case for a curved space-time, presents the mathematical background (tensor calculus, Riemannian geometry), discusses the Einstein equation and its solutions (including black holes and Penrose processes), and considers the energy-momentum tensor for various solutions. In addition, a section on relativistic astrophysics discusses stellar contraction and collapse, neutron stars and their equations of state, black holes, and accretion onto collapsed objects, with a final section on cosmology discussing cosmological models, observational tests, and scenarios for the early universe. This fully revised and updated second edition includes new material on relativistic effects, such as the behavior of clocks and measuring rods in motion, relativistic addition of velocities, and the twin paradox, as well as new material on gravitational waves, amongst other topics.
Masers are the microwave analogue of lasers; there are many astronomical sources of natural maser emission, including gas around forming and dying stars, and around supermassive black holes. These bright sources of microwaves are fascinating in their own right and provide unique abilities to probe details of astronomical sources. Molecular maser emission studies address important questions in the formation and evolution of stars, the structure of our Milky Way Galaxy, the characteristics of supermassive black holes, and fundamental parameters of cosmology. More than 100 astronomers from around the world gathered in Cagliari, Sardinia, for IAU Symposium 336 to discuss the latest findings related to masers. These proceedings summarize state of the art observations and theories pertaining to astrophysical masers and their environments, for graduate students and researchers. As new radio telescope facilities come online, observations of masers will continue to shed light on a broad range of important astrophysical problems.

An Introduction to Molecular Clouds describes the formation of molecular clouds and the innovative features of molecular clouds with different physical parameters. In this book, Jean-gravitational instability is discussed with different physical parameters, which is the major cause of the formation of molecular clouds in the interstellar medium (ISM), and the way molecular clouds are formed in the astrophysical plasma environment is described. The authors aim to determine the basic conditions responsible for the formation of heavenly bodies in the universe. The book deals with radiative instability in a variety of conditions incorporating different physical parameters such as viscosity, rotation, permeability, porosity, thermal conductivity, Hall current, Finite ion Larmor radius corrections, finite electrical resistivity, radiative heat-loss functions and finite electron inertia, both in gaseous plasma and quantum plasma environments.
Humanity's first reusable spacecraft and the most complex machine ever built, NASA's Space Shuttle debuted with great promise and as a dependable source of wonder and national pride. But with the Challenger catastrophe in 1986, the whole Space Shuttle program came into question, as did NASA itself, so long an institution that was seemingly above reproach. Wheels Stop tells the stirring story of how, after the Challenger disaster, the Space Shuttle not only recovered but went on to perform its greatest missions. From the Return to Flight mission of STS-26 in 1988 to the last shuttle mission ever on STS-135 in 2011, Wheels Stop takes readers behind the scenes as the shuttle's crews begin to mend Cold War tensions with the former Soviet Union, conduct vital research, deploy satellites, repair the Hubble Space Telescope, and assist in constructing the International Space Station. It also tells the heart-wrenching story of the Columbia tragedy and the loss of the magnificent STS-107 crew. As complex as the shuttle was, the people it carried into orbit were often more so-and this is their story, too. Close encounters with astronauts, flight controllers, and shuttle workers capture the human side of the Space Shuttle's amazing journey-and invite readers along for the ride.

Il libro e basato sulle lezioni attualmente tenute dall'autore presso l'Universita di Bari, ed e progettato in modo da rappresentare un testo di riferimento il piu possibile moderno, completo e autosufficiente per i corsi semestrale di Cosmologia, Astrofisica o Fisica Astroparticellare che compaiono nel piano di studi della Laurea Magistrale in Fisica e in Astronomia. Contiene gli elementi di base della cosmologia relativistica, del modello cosmologico standard e del suo completamento inflazionario. E' organizzato per servire da traccia ad un corso di cosmologia di stampo teorico, ma cerca di non perdere mai di vista il confronto con i principali risultati osservativi: molta attenzione viene infatti dedicata alla fenomenologia dei fondi cosmici, e in particolare alla radiazione gravitazionale fossile perche la sua rivelazione, diretta o indiretta, potrebbe dare indicazioni cruciali sulla scelta del corretto modello per l'Universo primordiale. Non mancano infine alcuni accenni ad argomenti di interesse emergente, di tipo teorico-fenomenologico, come lo studio dell'effetto di "deriva" del redshift, la cosmologia delle membrane, e il problema delle medie cosmologiche fatte su ipersuperfici spaziali (o nulle) non omogenee."
La realizzazione e il lancio nello spazio di satelliti o sonde attraverso missili o navette spaziali sono un esempio di attivita industriale di enorme complessita e di lungo periodo. Lo sviluppo di un programma spaziale prevede la realizzazione di vari sistemi costituenti: il segmento spaziale, cioe i lanciatori per l'accesso allo Spazio, i satelliti o le sonde, le infrastrutture spaziali abitate da astronauti oppure robotizzate; e il segmento di terra che consente agli operatori sulla terra di controllare i sistemi nello spazio e di fruire delle applicazioni derivanti dal loro uso. Il settore e di per se peculiare dato l'ambiente extra-atmosferico ove si troveranno ad operare astronauti o sonde robotizzate, pertanto la manifattura dei sistemi spaziali e una pratica a meta strada tra la scienza esatta e l'artigianato di elevatissima qualita. Le metodologie e i processi realizzativi dei programmi spaziali hanno pero avuto il pregio nel passato di costituire, sin dagli anni '60, un modello di riferimento per altri settori industriali proprio a causa della loro unicita tecnologica e produttiva. E oggi le metodologie di gestione dei programmi spaziali sono standardizzate e consolidate. Gli elementi trattati in questo libro intendono avvicinare il lettore alle specificita gestionali della concezione, del finanziamento e della messa in essere di un programma spaziale, una tra le piu complesse attivita umane influenzate da fattori storici, scientifici, economici e politici.

During the last twenty years, dramatic improvements in methods of observing astrophysical phenomena from the ground and in space have added to our knowledge of what the universe is like now and what it was like in the past, going back to the hot big bang. In this overview of today's physical cosmology, P.J.E. Peebles shows how observation has combined with theoretical elements to establish the subject as a mature science, while he also discusses the most notable recent attempts to understand the origin and structure of the universe. A successor to Peebles's classic volume Physical Cosmology (Princeton, 1971), the book is a comprehensive overview addressed not only to students but also to scientists active in fields outside cosmology. The first chapter of the work presents the elements of physical cosmology, including the history of the discovery of the expanding universe. The second, on the cosmological tests that measure the geometry of spacetime, discusses general relativity theory as the basis for the tests, and then surveys the broad variety of ways the tests can be applied with the new generations of telescopes and detectors. The third chapter deals with the origin of galaxies and the large-scale structure of the universe, and reviews ideas about how the evolution of the universe might be traced back to very early epochs when structure originated. Each section of these chapters begins with an introduction that can be understood with no special knowledge beyond undergraduate physics, and then progresses to more specialized topics. P.J.E. Peebles is Albert Einstein Professor of Science at Princeton University. He is a Fellow of the American Academy of Arts and Sciences and the Royal Society.

Recent discoveries in astronomy and relativistic astrophysics as well as experiments on particle and nuclear physics have blurred the traditional boundaries of physics. It is believed that at the birth of the Universe, a whirlwind of matter and antimatter, of quarks and exotic leptons, briefly appeared and merged into a sea of energy. The new phenomena and new states of matter in the Universe revealed the deep connection between quarks and the Cosmos. Motivated by these themes, this book discusses different topics: gravitational waves, dark matter, dark energy, exotic contents of compact stars, high-energy and gamma-ray astrophysics, heavy ion collisions and the formation of the quark-gluon plasma in the early Universe. The book presents some of the latest researches on these fascinating themes and is useful for experts and students in the field.
Nuclear astrophysics is, in essence, a science that attempts to
understand and explain the physical universe beyond the Earth by
studying its smallest particles. "Cauldrons in the Cosmos," by
Claus E. Rolfs and William S. Rodney, serves as a basic
introduction to these endeavors. From the major discoveries in the
field to a discussion of the makeup of stars to an explanation of
standard lab techniques, this text provides students and scientists
alike a thorough and fascinating survey of the accomplishments,
goals, and methods of nuclear astrophysics. A classic in its field,
"Cauldrons in the Cosmos" will surely remain an important reference
